test(sanctoral_ef): fix round 1 (F8) -- guard against wholesale name.pl loss

The previous commit's bootstrap_sanctoral.ml change (name.pl optional) is
correct and verified not to silently drop a present name, but nothing in
the suite would have caught a regeneration that dropped name.pl WHOLESALE
-- the exact defect lectio itself shipped once (a regeneration that lost
all 322 Polish names, only caught because that project's own review ran
cmd/lectio-ef-dump, which happens to include name fields; this project's
own test_load_and_counts checks entry/status/rank counts only, none of
which move if every name.pl vanishes).

Added a 322-of-327 count assertion (5 legitimately lack it, matching
parse_names's own list), independently re-derived: `grep -c '^name.pl'
tridentine-calendar.ini` = 322, cross-checked against `grep -c '(pl'
data/ef/sanctoral.sexp` = 322 exactly.
